    SubjectRe: [2.5.54 - Oops] CPUFreq [Was: Re: [2.5.54] OOPS: unable to handle kernel paging request]
    Date
    Hello,

    Good news !
    Using the patch :
    http://www.brodo.de/cpufreq/cpufreq-2.5.54-p4-1
    it is now booting fine !

    1 [11:40] rol@donald:~> cat /proc/cpufreq
    minimum CPU frequency - maximum CPU frequency - policy
    CPU 0 302902 kHz ( 12 %) - 2423222 kHz (100 %) -
    performance

    Cool...
